SO CONFUSED: A 30 point drop for removing this dispute comment??

Hi everyone...this is my first post. I have a bit of a dilemma. My wife and I are trying to qualify for a home loan. My scores were 710, 706 and 700 with Equifax being the mid score at 706. The underwriter came back and questioned one old credit card that I had disputed (shown below). I honestly didn’t even realize it was still listed as open on Equifax. It is closed on Experian and TransUnion. Anyhow, I contacted Equifax and had the dispute removed. My credit score dropped 29 points instantly…any idea why? Would letting them know it is closed help?

You can buy the same FICO your lender uses here on myFICO. Equifax.com also sells the same FICO but it's hard to find and they push their FAKO as you know. And of course you can get it from your lender.

† Credit cards for FICO Score ranges: The score ranges are guidelines based on internal myFICO analysis of actual applicant approvals, and having a FICO Score in a particular range does not guarantee you will be approved for credit cards recommended in that range. These ranges were not provided by any card issuer.

IMPORTANT INFORMATION: All FICO® Score products made available on myFICO.com include a FICO® Score 8, along with additional FICO® Score versions. Your lender or insurer may use a different FICO® Score than the versions you receive from myFICO, or another type of credit score altogether. Learn more
